Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • (1) Age ≥ 18 years old, regardless of gender. (2) Diagnosed with peripheral lung cancer, with the maximum diameter of the tumor ≤ 3 cm and the number of tumors ≤ 3. (3) The lesion to be ablated is evaluated as suitable for bronchoscopy-guided cryoablation treatment. (4) The subject refuses or is deemed unsuitable for radiotherapy/chemotherapy, or shows no response to previous radiotherapy/chemotherapy, or experiences disease progression after radiotherapy/chemotherapy. (5) Assessed as ineligible for surgery or refuses surgery and radiotherapy, consents to receive initial ablation treatment, and signs the informed consent form.

Who cannot join

  • (1) Diffuse lesions in both lungs where ablation treatment is unlikely to improve the condition. (2) Presence of hilar lymph node metastasis or extrapulmonary metastasis as indicated by examinations within 1 month before the operation (except for extrapulmonary metastasis that has been controlled by local treatment). (3) Presence of contraindications for bronchoscopy, or inability to tolerate or cooperate with bronchoscopy. (4) Severe bleeding tendency, uncorrectable coagulation dysfunction (prothrombin time > 18 s, prothrombin activity < 40%). (5) Platelet count < 70×109/L, or anticoagulant and/or antiplatelet drugs have not been discontinued for more than 1 week before ablation (except for prophylactic use of low-molecular-weight heparin before the operation). (6) Severe impairment of lung function, with maximum ventilation < 40%. (7) Concurrent with other tumors and extensive metastasis, with an expected survival period of less than 3 months. (8) Poor general condition (multiple metastases throughout the body, severe infection, high fever), infectious and radiation-induced inflammation around the lesion, obvious cachexia, severe insufficiency of vital organs, severe anemia and nutritional metabolic disorders that cannot be improved in the short term. (9) Eastern Cooperative Oncology Group (ECOG) performance status score > 2. (10) The lesion to be ablated has received radiotherapy within the past 6 months. (11) Presence of active hepatitis B, active hepatitis C, history of human immunodeficiency virus (HIV) infection (known positive for HIV 1/2 antibodies), or other active infections that may affect the patient's treatment as judged by the investigator. (12) Accompanied by epilepsy, history of mental illness or cognitive impairment. (13) Pregnant or lactating women, and male or female patients planning to conceive or become pregnant during the trial. (14) Participation in any other clinical trial within 3 months before signing the informed consent form (except for non-interventional studies). (15) Other circumstances considered inappropriate for participation in this clinical trial by the investigator.

About this study

The goal of this single-arm clinical trial is to evaluate the safety and efficacy of robotic bronchoscopy system (RBS)-assisted cryoablation in the treatment of primary lung cancer in adult patients (aged ≥18 years) with histologically confirmed non-resectable primary lung cancer, regardless of gender. The main questions it aims to answer are:

Does RBS-assisted cryoablation achieve a predefined target technical success rate for complete tumor ablation under imaging guidance? Is the incidence of severe procedure-related adverse events within an acceptable safety threshold ?

Read more

Participants will:

Provide written informed consent for RBS-assisted cryoablation.

Undergo pretreatment evaluations, including:

Multimodal imaging (CT/PET-CT) for tumor localization and staging. Pulmonary function tests and cardiopulmonary risk assessment. Receive RBS-guided cryoablation therapy under general anesthesia. Be monitored for intraoperative complications and postoperative adverse events for 72 hours.

Complete follow-up assessments at 1, 3, 6, and 12 months post-procedure, including:

Contrast-enhanced CT scans to evaluate local tumor control. Documentation of symptom progression and quality-of-life metrics.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adverse events incidence

    The proportion of complications related to cryoablation (such as bleeding, pneumothorax, infection, etc.) that occurred in the subjects after cryoablation treatment.

    Measured: 1 month after procedure

Questions about this trial

What is this clinical trial studying?

A study testing robotic bronchoscopy system in people with Lung Cancer Patients, run by Guangzhou Medical University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 18 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Changhao Zhong (020-81566640, vast1982@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events incidence (time frame: 1 month after procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06832956, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2025.
